void gtk_menu_shell_set_take_focus ( GtkMenuShell* menu_shell, gboolean take_focus )
TRUE (the default) the menu shell will take
the keyboard focus so that it will receive all keyboard events
which is needed to enable keyboard navigation in menus.
FALSE is useful only for special applications
like virtual keyboard implementations which should not take keyboard focus.
take_focus state of a menu or menu bar is automatically
propagated to submenus whenever a submenu is popped up, so you
don’t have to worry about recursively setting it for your entire
menu hierarchy. Only when programmatically picking a submenu and
popping it up manually, the
take_focus property of the submenu
needs to be set explicitly.
Note that setting it to
FALSE has side-effects:
If the focus is in some other app, it keeps the focus and keynav in the menu doesn’t work. Consequently, keynav on the menu will only work if the focus is on some toplevel owned by the onscreen keyboard.
To avoid confusing the user, menus with
take_focus set to
should not display mnemonics or accelerators, since it cannot be
guaranteed that they will work.
